Patented July 29, 1930 UNITED TAT-ESPATENT, OFFICE GEORGE i3. ALLEN, or ATLANTA, GEORGIA LIQUID-PURIFYING DEVICE Application'filed September 6-, 1927. Serial No. 217,793.

This invention relates to a device for purifying liquids, and more particularly bevelages suchas root beer, gingerale and the like. An important object of the invention isto provide a porous container-in which is merged'i'n the body of a liquid whereby the' latter will be aged; purified and de(' doriz ed.-

- the bedy of the purifying agent to permit the xlatter to take up '[foreign matter from the arranged a body of a purifying a cut such as- 'charc'oal'orthe like and adapte to be sub-- further object is to provide a device of the above mentioned character-which may be made pf fahric or similar porous material to permit the circulation of the liquid through liquid, whereby the latter will be rapidly aged, purified and de-odorized.

A, further object-is to provide a cloth or similar bag divided to form a compartment for a purifying agent and a compartment adapted tofcontain crushed stone or the like i whereby the specific gravity of the device will be'greater than'that of the liquid in'whichz it is used so vtli' at it willsink in the liquid.

-A further object is to 'provide'a' cloth orsimilar hag which is vgreatly elongated and is adapted to assume a vertical position in a container for liquids whereby the device may be centrally arranged within the liquid to more efficiently permit circulation of thelatthrough the purifyingmaterial, V

A further object is to provide a device of the above mentioned character wherein the lower endof the ,bag containscrushed stone or the like to provide weight means and wherein the greater portion of the upper therein and will remainin an upright posi-' end of the bag contains a purifying agent of lighter specific gravity than the liquid in whichvthe device is to be used, the specific gfi'avity of the device as a whole being greater t an that of the liquid whereby it will sink showing the device in position therein, parts being shown in elevation, and

Figure 2 is a detail. perspective of the device. I

The device forming the subject matter of the present invention is adapted to age, purify and deodorizeliquids of. various characters such as root beer, gingerale and the like, and the liquid may be placed in any suitable container. -In the present instance I have illustratedth'e container as comprising a glass ,jar 10 having a screwihreadedcap 11 and containing a body of a'liq uid 12.

The device'forming thesubj'ect matter of I the presentinvention comprises a ba'g113 preferably formed of textile material w ereby it -will he porous to permit the circulation of the liquid therethrough. Thebag isprovided centrally thereof with a string 15 or other Suitable means adapted to divide the-bag into a relatively smalllovver compartment 16 and 1; v a relatively long upper section 17. Weight means 18 is preferably arranged in the lower I "Section of the: bag, and such means may";

comprise crushed stone or the like, for a purpose to. be described.'-. The elongated upp'er v section of the bag is provided with a bodyof a purit'ying agent19, such as charcoal or the like, and the upper end of the bag may, be

tied with a string 20 or the like. The operation of the device is as follows: The liquid'to be treated is placed in the container and suffic'ient space is left in the container to accommodate the purifying device. Thezlatteris placed in position in thecontainer as shown in Figure 1. The specific gravity of .the purifying agent is materially less thanthat-of'th'e liquid, while thespecific gravity, of the crushed stone or other weightmg means is materially greater than the liquid. The proportion of the materials employed is such that the specific gravity of the I device as a whole is greater than that of the liquid so that it will sink to the bottomof the container, and it will be obvious that the. weightedend ofthe bag will rest on the bottom of the container, While the latter, as awhole, will assume an upright position. The device preferably is'placed centrally of the container as shoWn-inFigure 1 so'that all por tions of the liquid will be more evenly subjected to the action of the purifying agent. 7

The porous .bag permits the material to circulate therethrough to be subjected to the aetion of the purifying agent, and the latter Will age, purify and deodorize the liquid in a much shorter time than can be accomplished by the use of charred kegs or the like. The device has the additional advantage that it may be used in glass, porcelain, and similar containers, and the purifying agent is retained wholly within the bag, thus rendering it unnecessary to filter the liquid. The bag may be left in the liquid for any desired length of time and it Will be apparent that the longer the bag remains in the liquid, the greater Will be-the extent of the desired action.

It is to be understood that the form of my invention herewith shown and described is to 0 be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

I claim: 1. A device of the character described comrisin an elon ated orous fabric container adapted to be arranged in a body of a liquid, liquid purifying means arranged in said container and substantially filling the latter from the top thereof to a point spaced from the bot tom thereof, said means possessing a specific ravity less than the specific gravitv of the liquid, and material of greater specific gravity than -said purifying means arranged in the bottom of said container and substantially filling the latter from the bottom thereof to the lower end of said purifying means, said material providing meansfor causing said container to maintain a substantially vertical position in said liquid.

2. A device of the character described comprising an elongated porous fabric container adapted to be arranged in a body of a liquid, means for dividing said container into two integral compartments, one compartment being substantially larger than the other, liquid purifying means arranged in the larger of saidcompartments, said purifying means possessing a specific gravity less than the -specific gravity of the liquid, and material arranged in the other of said compartments of greater specific gravity than said purifying means and of greater Weight than the Weight of. said purifying means providing means for-causing said container to maintain a substantially vertical position insaid liquid,

In testimony whereof I affix my signature.

GEORGE B. ALLEN.
